Product Description

 

Polyvinyl alcohol (PVA)

         Polyvinyl alcohol (PVA) is a water-soluble polymer with a large number of side - hydroxyl groups in the molecular chain, so it is also regarded as a macromolecular polyol. PVA is made of vinyl ace tate (VAc) monomer after polymerization and alcoholysis, according to the different raw materials, PVA preparation method can be divided into two kinds, one is to prepare vinyl ace tate as raw material; The other is acetyl ene (calcim carbide acetyl ene or natural g as acet ylene) as the raw material to prepare vinyl acet ate, and finally the prepared vinyl ace tate is prepared by alco hol hydrolysis. Its performance is between plastic and rubber, with flexibility, oil resistance and chemical solvent resistance, gas barrier, water resistance after special treatment and many other excellent characteristics, widely used.
